Relationship between sleep position and otitis media in infants: The Japan environment and children's study

Area of Science:

• Pediatrics
• Otolaryngology
• Epidemiology

Background:

• Otitis media is a frequent infant illness with multiple known risk factors.
• Infant sleep position is associated with various health conditions.
• The link between otitis media and infant sleep position remains under-investigated.

Purpose of the Study:

• To investigate the association between infant sleep position and the incidence of otitis media.
• To analyze sleep position data in relation to otitis media occurrence in infants up to six months old.

Main Methods:

• Utilized data from the Japan Environment Children's Study, including 85,731 infants.
• Employed multivariate logistic analysis to assess the relationship between sleep position and otitis media incidence.
• Conducted stratified analyses based on infant ability to turn over at six months.

Main Results:

• A significantly higher incidence of otitis media was observed in infants sleeping in the prone position (adjusted odds ratio, 1.206).
• The association between prone sleeping and otitis media persisted across all subgroups, including those who could turn over.
• The findings were consistent regardless of whether the infant could independently change position.

Conclusions:

• Infants aged six months and younger sleeping in the prone position face an increased likelihood of developing otitis media.
• Sleep position counseling for parents and caregivers could be a valuable strategy for otitis media prevention.
• Modifying infant sleep position may reduce the incidence of otitis media.
